Thank you for the explanation! That helped me understand what's going on
in the collect better. Yes, name is defined. This is actually from a
rails app and colors is the table which has a name attribute (among
others), so this line works great if I want to show all the colors. In
another post a few minutes ago, I explained how I am actually using this
in a call to another function from in ajax_scaffold. I was trying to
simplify it somewhat to get at the core of the problem, but I think in
my lack of understanding, I simplified too much


Cheers,
Rosina
